| 摘 要： | 以三角洲前缘低渗透砂岩储层为例,综合应用多学科理论和技术,建立了长期注水开发低渗透砂岩油藏的动态模型和剩余油仿真模型,研究了剩余油分布规律,并建立了高含水率开发阶段储层微观剩余油的三类分布模式.研究结果表明,油藏开发流体动力地质作用控制了不同含水期三角洲前缘低渗透砂岩油藏参数的演化,储层宏观物性参数及微观孔喉网络演化有利于驱油.油藏仿真模型是揭示长期注水开发油藏储层三维空间演化规律、预测和评价剩余油分布的有效技术手段.

| Abstract: | The simulation model of remaining-oil distribution and the dynamic model for oil reservoir of low-permeability sandstone in the long-term waterflooding were developed, according to comprehensively multi-disciplinary theory and technology. Three kinds of models for micro remaining-oil distribution of reservoirs in high water-cut development stage were established. The distribution laws of remaining oil in delta-front low-permeability sandstone reservoirs were analyzed. The result showed that the evolution of the parameters for delta-front low-permeability sandstone reservoir was controlled by the hydrodynamic geologic process during the oil-reservoir development. The reservoir parameters for describing the macroscopic physical property and microcosmic pore-throat evolution are favorable to oil displacement. The simulation model of oil reservoir is the effective technological means for displaying the threedimensional evolution rule of reservoir in long-term waterflooding, predicting and estimating the distribution of remaining oil. |
